Observing my spouse with large breasts being pleasured by my closest companion in the bedroom

I was in the bedroom with my best friend, who had been over to the house, when my spouse decided to join us. She had recently gotten some rather large breasts, which were quite noticeable. My spouse decided to have my best friend pleasure her, and I decided to watch. The sight of my spouse being pleasured by my best friend was rather arousing, and I could not resist joining in. My spouse allowed me to pleasure her as well, and she then straddled my best friend, and I joined in, pleasuring her from behind. After a bit of cock sucking and cowgirl riding, my spouse was ready for a big load, and she eagerly accepted it, taking it in her mouth.
